The subscription could not be found at AzureChinaCloud

[sfairat15]

We are trying to use azure-metric-exporter at our Azure China Cloud.

We set up next env variables:

AZURE_ENVIRONMENT=AzureChinaCloud
AZURE_AD_RESOURCE=https://management.chinacloudapi.cn/

But get errors:

{"file":"probe_metrics_list.go:66","func":"func1","level":"error","msg":"resources.Client#List: Failure responding to request: StatusCode=404 -- Original Error: autorest/azure: Service returned an error. Status=404 Code=\"SubscriptionNotFound\" Message=\"The subscription '**REDACTED**' could not be found.\"","paramFilter":["resourceType eq 'Microsoft.DBforMySQL/servers'"],"paramMetric":["cpu_percent,memory_percent,io_consumption_percent,storage_percent,storage_used,storage_limit,serverlog_storage_percent,serverlog_storage_usage,serverlog_storage_limit,active_connections,connections_failed,seconds_behind_master,backup_storage_used,network_bytes_egress,network_bytes_ingress"],"paramSubscription":["**REDACTED**"],"requestPath":"/probe/metrics/list"}

So, we added next env variable for debugging:

AZURE_GO_SDK_LOG_LEVEL=DEBUG

Found next log at console:

Resolution:

Looks like application should use another methods at azure_insights.go file, instead of simple NewClient and NewMetricsClient calls, app should use another with BaseUrl parameter, according to Azure Cloud.
By default, BaseUrl point to https://management.azure.com/.
